Title: Preparing crystalline cefazolin sodium by solvent¹sublimation.
IPC: A61P31/04
Filed: 1977-11-24
Abstract: Sterile, essentially crystalline cefazolin sodium for parenteral administration is prepared by a freeze-drying process wherein a C1-C3 alcohol-water solution of cefazolin sodium containing about 10 percent by volume of the C1-C3 alcohol is chilled slowly from room temperature to about -10 DEG C. over a 3-12 hour period and then rapidly cooled to -30 DEG to about -40 DEG C. and held for 1-2 hours before subjecting said frozen solution to a high vacuum and a moderate amount of heat to sublime the frozen solvent therefrom. The resulting powder dissolves rapidly in acceptable pharmaceutical diluents.

Patent NO-793792-L (NO)
Inventor: TEGLUND LARS
IPC: E03F7/00
Filed: 1979-11-22
Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.

Abstract: A clock regenerator is designed as a phase locked loop (PLL) and comprises a phase detector (DET) which compares the phase of the input signal (Sp) with that of the output signal (Sa), the frequency of the phase detector being approximately N times smaller than the oscillator frequency. In the phase detector (DET), there are obtained from a regenerated output signal (Sa) two signals delayed by L/N periods, wherein L is a small integer, in order to form therefrom a pulse window comprising at least three zones. The clock regenerator comprises a loop filter (FIL) with a counter, the status of which is recorded in a logic circuit which controls a programmable divisor (DIV) in such a way that when the edges of the input pulse (Sp) fall in the central most zone, the counter counts toward zero and no correction is brought about.
